Answer:
Step-by-step explanation:
f ( x ) = 3 x + 2 − √ x − 3
f(19) = 3*19 + 2 -
= 57 + 2 -4
= 55
Answer:
Dilation
Step-by-step explanation:
Transformation is the movement of objects in coordinate plane.A function f will map a set X to itself. f:X→X. Dilation is a transformation that produces an image of the same shape as the original but of different size.In dilation angle measures are preserved where as lengths of segments are not preserved.
-2(5y-20) - 5y = -5
-10y + 40 - 5y = -5
-15y + 40 = -5
-15y = -45, y = 3
x = 5(3) - 20
x = 15 - 20, x = -5
Solution: x = -5, y = 3... or (-5,3)
Problem 1
One possible answer is y = -x+5
This equation has a slope of -1 as does the first equation y = -x+3. Parallel lines have equal slopes but different y intercepts.
You can change the "+5" to any number you want.
=====================================
Problem 2
One possible answer is y = (3/4)x - 2. Like before, parallel lines have the same slope, just a different y intercept. The "-2" can be any number (negative or positive) you want as long as the slope remains 3/4.
